Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure.

[0003] Currently, more and more people are choosing to install air conditioners indoors to regulate the temperature of the indoor air. Wall-mounted air conditioners are one type of air conditioner, and their flexible installation location, high cost-effectiveness, and wide applicability make them the first choice for most families when selecting an air conditioner.

[0004] In existing technologies, the indoor unit of a wall-mounted air conditioner is usually installed directly opposite the bed. When the user is lying in bed, the airflow from the lower air outlet blows onto the bed, causing the user to feel a noticeable draft and resulting in a poor user experience. Utility Model Content

[0005] This application discloses a wall-mounted air conditioner indoor unit that can avoid the problem of air conditioning blowing on the bed when the user is lying in bed.

[0006] To achieve the above objectives, some embodiments of this application provide a wall-mounted air conditioner indoor unit, comprising: a casing, the casing including: a first side plate; a second side plate, the second side plate and the first side plate being disposed opposite to each other along the length direction of the casing; the casing having a casing air inlet and a casing air outlet, the casing air outlet including: an upper air outlet, the upper air outlet being disposed at the top front side of the casing; a lower air outlet, the lower air outlet being at least partially disposed at the bottom of the casing; a first side air outlet, the first side air outlet being disposed on the first side plate; and a second side air outlet, the second side air outlet being disposed on the second side plate; the casing containing: a heat exchanger, the heat exchanger being used to circulate air flowing into the casing... The airflow inside the casing undergoes heat exchange; a fan is used to introduce airflow into the casing through the air inlet, and after heat exchange by the heat exchanger, the airflow is sent into the room through the lower air outlet, the first side air outlet, the second side air outlet, and the upper air outlet; an air duct component is formed within the air duct component, the upper air duct is used to connect the first side air outlet, the second side air outlet, the upper air outlet, and the air outlet side of the fan, and the lower air duct is used to connect the air outlet side of the fan and the lower air outlet; wherein, the length of the upper air duct is greater than the length of the lower air duct; in the vertical direction, the first side air outlet and the second side air outlet are located near the top of the casing.

[0007] In related technologies, the conventional installation position of the indoor unit of a wall-mounted air conditioner is directly facing the bed. When the user is lying on the bed, the air conditioner blows out from the lower air outlet, and the airflow range of the lower air outlet will have the problem of blowing on the bed, which will cause the user to have a noticeable blowing sensation, resulting in a poor user experience.

[0008] In this embodiment, a first side air outlet is provided on the first side panel, and a second side air outlet is provided on the second side panel. The first and second side air outlets are connected to the air outlet side of the fan through an upper air duct. When the user is lying on the bed, air can be circulated through the first and second side air outlets. The air conditioning air blown from the first side air outlet flows outwards from the first side panel, and the air conditioning air blown from the second side air outlet flows outwards from the second side panel. This avoids the air conditioning air blowing directly onto the user on the bed, while simultaneously continuously exchanging heat with the indoor air through the air conditioning air blown from the first and second side air outlets. Furthermore, the first and second side air outlets are located near the top of the casing, allowing the air conditioning air blown from them to be closer to the top of the room, thus covering a larger area of ​​the room and enabling more thorough heat exchange with the indoor air.

[0009] In some embodiments of this application, the vertical length L of the first side air outlet and the second side air outlet is greater than the width M of the first side air outlet and the second side air outlet in the front-rear direction of the housing.

[0010] Thus, by setting the vertical length L of the first and second side air outlets to be greater than their width M in the front-to-back direction of the casing 1, the vertical coverage of the air supplied by the first and second side air outlets is increased. This enhances the uniform distribution of the air conditioning air blown from the first and second side air outlets within the room, allowing the air conditioning air to cover the indoor space more evenly and reducing the temperature difference between the upper and lower floors. Furthermore, the narrower front-to-back direction of the first and second side air outlets in the casing optimizes duct resistance and airflow organization, making the airflow more concentrated, improving energy efficiency, and reducing energy loss.

[0011] In some embodiments of this application, the housing further includes: a front panel located on the front side of the housing; the air duct component includes an upper air guide wall, the upper air guide wall including: a planar segment extending vertically; a curved segment, the lower end of which is connected to the upper end of the planar segment, and the upper end of which extends toward the front panel; the first side air outlet including: a first edge extending vertically; a second edge extending along the front-rear direction of the housing, and the front end of the second edge connecting to the lower end of the first edge; a third edge, the upper end of which is connected to the upper end of the first edge, and the lower end of the third edge connecting to the rear end of the second edge; the upper air guide wall extending through the first side panel along the length direction of the housing, such that the connection between the upper air guide wall and the first side panel forms the third edge.

[0012] Thus, the connection between the upper air guide wall and the first side plate forms a third edge, which means that the upper air guide wall itself becomes a local "skeleton" of the first side plate, which can improve the rigidity of the first side plate and reduce the resonance of the first side plate. The third edge is formed by the direct intersection of the edge of the upper air guide wall and the first side plate, eliminating the need to set an independent flange or sealing strip between the first side air outlet and the upper air duct, reducing the number of parts, reducing assembly errors, and avoiding the problem of air leakage.

[0013] In some embodiments of this application, the first side air outlet and the second side air outlet are at the same height in the vertical direction.

[0014] In this way, by setting the first and second air outlets at the same height, the airflow resistance characteristics from the upper air duct to the first and second air outlets are made completely consistent, thus ensuring that the air volume and air pressure of the air outlets on both sides are balanced. This allows cool air to cover the left and right spaces of the room simultaneously and in equal amounts, and to sink evenly, eliminating any potential temperature differences between the left and right sides of the room and achieving temperature uniformity and comfort.

[0015] In some embodiments of this application, the area of ​​the first side air outlet and the second side air outlet is 3500 mm². 2 ~4450mm 2 .

[0016] Thus, by setting the area of ​​the first side air outlet and the second side air outlet to 3500mm² 2 ~4450mm 2This design minimizes airflow resistance from the first and second air outlets, ensuring sufficient airflow and reducing their footprint on other components, thus maintaining a harmonious and aesthetically pleasing appearance. Furthermore, it avoids the situation where excessively large areas of the first and second air outlets would result in them being too close to the fan's outlet in the vertical direction, preventing insufficient airflow within the upper duct and hindering airflow from exiting the outlets. This design ensures smooth airflow from both sides.

[0017] In some embodiments of this application, the width M of the first side air outlet and the second side air outlet along the front-rear direction of the housing is 28mm to 42mm.

[0018] In this way, by setting the width M of the first and second air outlets along the front and rear direction of the casing to be 28mm to 42mm, it ensures that the first and second air outlets have sufficient air outlet area along the front and rear direction of the casing, thus guaranteeing the air volume of the first and second air outlets, without excessively increasing the size of the casing in the front and rear direction, and avoiding excessive increase in the space occupied by the wall-mounted air conditioner indoor unit.

[0019] In some embodiments of this application, the length L of the first side air outlet and the second side air outlet in the vertical direction is 125mm to 155mm.

[0020] Thus, by setting the length L of the first side air outlet and the second side air outlet to 125mm to 155mm, the air outlet area of ​​the first side air outlet and the second side air outlet in the vertical direction is guaranteed without increasing the vertical dimension of the casing, and the air volume of the first side air outlet and the second side air outlet is guaranteed.

[0021] In some embodiments of this application, the air duct assembly further includes: a volute, the volute being located at the rear side of the fan and arranged around a portion of the fan; a volute tongue, the volute tongue being located at the front side of the fan and arranged opposite to the volute; and in the vertical direction, the distance H from the lower end of the first side air outlet to the lower end of the volute tongue is 60mm to 75mm.

[0022] Thus, by setting the distance H from the lower end of the first side air outlet to the lower end of the volute tongue to 60mm~75mm, sufficient flow distance of the air conditioning air is ensured in the upper air duct, avoiding the air conditioning air directly facing the outlet resistance of the first and second side air outlets from the air outlet side of the fan. This ensures that the air conditioning air can be blown to both sides after being blown out from the first and second side air outlets, and also ensures the air volume of the first and second side air outlets.

[0023] In some embodiments of this application, a main air duct is further formed within the air duct component. The air inlet end of the main air duct is connected to the air outlet side of the fan, and the air outlet end of the main air duct is connected to the upper air duct and the lower air duct, respectively. The housing is further provided with an air guide component, which is rotatably disposed within the main air duct and is switchable between an open position, a first position, a second position, and a diversion position. When the air guide component is in the open position, both the upper and lower air ducts are connected to the main air duct. The air outlet is connected; when the air guide is in the first position, the air guide can close the lower air duct so that the upper air duct is connected to the air outlet of the main air duct; when the air guide is in the second position, the air guide can close the upper air duct so that the lower air duct is connected to the air outlet of the main air duct; when the air guide is in the diversion position, the air guide is configured to divert the airflow sent out by the main air duct so that the diverted airflow enters the upper air duct and the lower air duct respectively.

[0024] In this way, the rotation of the air guide can switch between multiple air supply modes to meet the needs of diverse scenarios.

[0025] In some embodiments of this application, the housing is further provided with: a first air guide plate, which is rotatably disposed at the upper air outlet to open or close the upper air outlet; and a second air guide plate, which is rotatably disposed at the lower air outlet to open or close the lower air outlet.

[0026] In this way, by using the first and second air guide plates to close the upper and lower air outlets, the air conditioning air is blown out from the first and second side air outlets under pressure, eliminating the need for a separate drive mechanism to drive the air conditioning air out from the first and second side air outlets, thus saving manufacturing costs.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The technological development trends for these products primarily focus on intelligentization, energy conservation and environmental protection, optimized user experience, and the application of new materials. Optimized user experience is achieved through design innovation and functional enhancement to meet consumers' demands for health, convenience, and personalization.

[0056] As an important type of household appliance, wall-mounted air conditioner indoor units can regulate indoor temperature by delivering cool air into the room, thus lowering the indoor temperature and keeping it within a comfortable range.

[0057] In related technologies, the conventional installation position of a wall-mounted air conditioner indoor unit is directly facing the bed. When the user lies on the bed, the air conditioner blows out from the lower air outlet, and the airflow range of the lower air outlet will have the problem of blowing on the bed, which will cause the user to have a noticeable feeling of being blown by the air. If it is an air conditioner with an upper air outlet, the air conditioner air will flow along the top wall of the room, and the problem of blowing on the bed will still exist.

[0058] Based on this, this application provides a wall-mounted air conditioner indoor unit that can avoid the problem of air conditioning blowing on the bed when the user is lying in bed.

[0059] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0060] Please see Figure 1 This application provides a wall-mounted air conditioner indoor unit 100, which includes a housing 1 and houses various functional components of the wall-mounted air conditioner indoor unit 100.

[0061] See Figures 1 to 3 The housing 1 includes a first side plate 11 and a second side plate 12, with the second side plate 12 and the first side plate 11 arranged opposite to each other along the length of the housing 1.

[0062] It should be noted that the length direction of housing 1 is... Figure 4 The direction from left to right or from right to left.

[0063] like Figure 3 As shown, the housing 1 is provided with a housing air inlet 13 and a housing air outlet. The housing air inlet 13 is used to guide airflow into the interior of the housing 1, and the housing air outlet is used to guide airflow into the room.

[0064] The air outlet of the housing includes an upper air outlet 144, which is located on the top front side of the housing 1, and some airflow is blown out from the upper air outlet 144.

[0065] The housing air outlet also includes a lower air outlet 141, which is at least partially located at the bottom of the housing 1, and some airflow is blown out from the lower air outlet 141.

[0066] like Figure 2 and Figure 3 As shown, the air outlet of the housing also includes a first side air outlet 142, which is disposed on the first side plate 11.

[0067] The housing 1 also includes a second side air outlet 143, which is disposed on the second side plate 12.

[0068] A heat exchanger 2 is installed inside the casing 1. The heat exchanger 2 is used to exchange heat with the airflow flowing into the casing 1. The heat exchanger 2 is a heat exchanger that utilizes the characteristic that liquid low-temperature refrigerant is easy to evaporate under low pressure. By absorbing heat from the medium being cooled, it lowers the temperature of the surrounding air, thereby achieving a cooling effect. The cooled air after passing through the heat exchanger 2 is returned to the room through the air supply system, providing a comfortable indoor environment. Especially in the hot summer, the cooling effect of the heat exchanger 2 can significantly reduce the indoor temperature and improve people's living comfort.

[0069] In this embodiment, heat exchanger 2 is a finned heat exchanger. Of course, heat exchanger 2 can also be other types of heat exchangers, and this embodiment does not specifically limit it.

[0070] like Figure 5 and Figure 9 As shown, a fan 3 is also provided inside the casing 1. The fan 3 is used to introduce airflow into the casing 1 through the air inlet 13, and after heat exchange in the heat exchanger 2, the airflow is sent into the room through the lower air outlet 141 and the first side air outlet 142. The fan 3 can introduce airflow into the interior of the casing 1, so that after the airflow is heat exchanged in the heat exchanger 2, the heat-exchanged airflow is sent back into the room under the action of the fan 3.

[0071] It should be noted that the fan 3 in this embodiment can be a cross-flow fan or other types of fans, and this embodiment does not specifically limit it.

[0072] The housing 1 is also provided with an air duct component 4, which forms an upper air duct 41 and a lower air duct 42. The upper air duct 41 is used to connect the first side air outlet 142, the second side air outlet 143, the upper air outlet 144 and the air outlet side of the fan 3. The lower air duct 42 is used to connect the air outlet side of the fan 3 and the lower air outlet 141.

[0073] The upper air duct 41 is longer than the lower air duct 42. In the vertical direction, the first side air outlet 142 and the second side air outlet 143 are located near the top of the casing 1.

[0074] In related technologies, the conventional installation position of the wall-mounted air conditioner indoor unit 100 is directly facing the bed. When the user lies on the bed, the air conditioner blows out from the lower air outlet 141. The airflow range of the lower air outlet 141 will have the problem of blowing on the bed, which will cause the user to have a noticeable blowing sensation, resulting in a poor user experience.

[0075] In this embodiment, a first side air outlet 142 is provided on the first side panel 11, and a second side air outlet 143 is provided on the second side panel 12. The first side air outlet 142 and the second side air outlet 143 are connected to the air outlet side of the fan 3 through the upper air duct 41. When the user is lying on the bed, air can be vented through the first side air outlet 142 and the second side air outlet 143. The air conditioning air blown out from the first side air outlet 142 flows towards the outside of the first side panel 11, and the air conditioning air blown out from the second side air outlet 143 flows towards the outside of the second side panel 12. This avoids the air conditioning air blowing directly onto the user on the bed, and at the same time, the air conditioning air blown out from the first side air outlet 142 and the second side air outlet 143 continuously exchange heat with the indoor air. Furthermore, the first side air outlet 142 and the second side air outlet 143 are located close to the top of the casing 1, so that the air conditioning air blown out by the first side air outlet 142 and the second side air outlet 143 is closer to the top of the room, so that the air conditioning air covers a larger indoor area and can exchange heat with the indoor air more fully.

[0076] For example, when the first side air outlet 142 and the second side air outlet 143 blow out cold air, the blown cold air is closer to the top of the room (i.e. the cold air has a higher initial position). The cold air sinks under the action of gravity and can mix more fully with the indoor air, so that the cold air can circulate and exchange heat in a larger space, thereby improving the overall air conditioning effect of the wall-mounted air conditioner indoor unit 100.

[0077] It should be noted that if the length of the upper air duct 41 is less than the length of the lower air duct 42, the air conditioning air will have a shorter flow distance along the upper air duct 41 before reaching the first side air outlet 142 and the second side air outlet 143. This will make it difficult for the air conditioning air to turn to the first side air outlet 142 and the second side air outlet 143, which will result in poor airflow from the first side air outlet 142 and the second side air outlet 143.

[0078] In this embodiment, by setting the length of the upper air duct 41 to be greater than the length of the lower air duct 42, the air conditioning air, after being blown out from the outlet side of the fan 3, can flow a longer distance along the upper air duct 41. This facilitates the change of the air conditioning air's radial flow direction to the axial flow direction when it reaches the first side air outlet 142 and the second side air outlet 143, ensuring that the air conditioning air can be smoothly blown out from the first side air outlet 142 and the second side air outlet 143 (e.g., Figure 7 As shown, Figure 7The arrows in the image indicate the direction of airflow from the air conditioner.

[0079] It should be noted that by setting the second side air outlet 143 on the second side plate 12, combined with the first side air outlet 142, the wall-mounted air conditioner indoor unit 100 can output air conditioning air on both sides along the length of the casing 1. The dual side air outlets can simultaneously deliver airflow to the left and right directions, so that the heat-exchanged air can quickly diffuse along the top of the room to the entire space, effectively eliminating the temperature blind spot in the far area when supplying air from one side, and ensuring the uniformity of the indoor temperature field.

[0080] In some embodiments, such as Figure 6 As shown, the vertical length of the first side air outlet 142 and the second side air outlet 143 is greater than the width of the first side air outlet 142 and the second side air outlet 143 in the front-rear direction of the housing 1. That is to say, the first side air outlet 142 and the second side air outlet 143 are elongated in shape.

[0081] It should be noted that the vertical direction is Figure 6 The direction from top to bottom or bottom to top in the middle, the front-to-back direction of the casing 1 is... Figure 6 The direction from left to right or from right to left in the middle.

[0082] If the vertical length L of the first side air outlet 142 and the second side air outlet 143 is less than or equal to the width M of the first side air outlet 142 and the second side air outlet 143 in the front-rear direction of the casing 1, the vertical coverage of the air conditioning air delivered by the first side air outlet 142 and the second side air outlet 143 will be small. This will result in poor heat exchange between the air conditioning air and the indoor air, leading to a large temperature difference between the upper and lower floors of the room. In this embodiment, by setting the vertical length L of the first side air outlet 142 and the second side air outlet 143 to be greater than the width M of the first side air outlet 142 and the second side air outlet 143 in the front-rear direction of the casing 1, the vertical coverage of the air delivered by the first side air outlet 142 and the second side air outlet 143 is increased, enhancing the uniform distribution of the air conditioning air blown from the first side air outlet 142 and the second side air outlet 143 in the room, allowing the air conditioning air to cover the indoor space more evenly, and reducing the temperature difference between the upper and lower floors of the room. Furthermore, the first side air outlet 142 and the second side air outlet 143 are narrower in the front-rear direction of the casing 1, which can optimize the airflow resistance and airflow organization, make the airflow more concentrated, improve energy efficiency, and reduce energy loss.

[0083] In some embodiments, such as Figure 8 and Figure 9 As shown, the housing 1 also includes a front panel 15, which is located on the front side of the housing 1. The front panel 15 constitutes the main appearance surface of the housing 1 facing the indoor space user, and usually adopts an aesthetically pleasing and clean design.

[0084] The air duct component 4 includes an upper air guide wall 43, which includes a planar section 431 that extends in the vertical direction.

[0085] The upper air guide wall 43 also includes a curved section 432, the lower end of which is connected to the upper end of the flat section 431, and the upper end of the curved section 432 extends to the front panel 15.

[0086] like Figure 6 As shown, the first side air outlet 142 includes a first edge 1421, which extends in a vertical direction.

[0087] The first side air outlet 142 also includes a second edge 1422, which extends along the front and rear direction of the housing 1, and the front end of the second edge 1422 is connected to the lower end of the first edge 1421.

[0088] The first side air outlet 142 also includes a third edge 1423. The upper end of the third edge 1423 is connected to the upper end of the first edge 1421, and the lower end of the third edge 1423 is connected to the rear end of the second edge 1422. The upper air guide wall 43 extends through the first side plate 11 along the length of the housing 1, so that the connection between the upper air guide wall 43 and the first side plate 11 forms the third edge 1423.

[0089] In other words, the shape of the third edge 1423 of the first side air outlet 142 is the same as the shape of the upper air guide wall 43. The third edge 1423 is formed at the connection between the upper air guide wall 43 and the first side plate 11, which means that the upper air guide wall 43 itself becomes a local "skeleton" of the first side plate 11, which can improve the rigidity of the first side plate 11 and reduce the resonance of the first side plate 11; and the third edge 1423 is formed by the direct intersection of the edge of the upper air guide wall 43 and the first side plate 11, eliminating the need to set an independent flange or sealing strip between the first side air outlet 142 and the upper air duct 41, reducing the number of parts, reducing assembly errors, and avoiding the problem of air leakage.

[0090] It should be noted that the second side air outlet 143 has the same structure as the first side air outlet 142. The second side air outlet 143 is composed of a fourth edge, a fifth edge, and a sixth edge. The connection between the upper air guide wall 43 and the second side plate 12 forms the sixth edge of the second side air outlet 143, which is similar to the effect of the connection between the upper air guide wall 43 and the first side plate 11 forming the third edge 1423 of the first side air outlet 142 in the above embodiment. This embodiment will not be described in detail here.

[0091] Of course, the first side air outlet 142 and the second side air outlet 143 can also be connected to the upper air duct 41 through separate pipes. A sealing device needs to be installed at the connection between the pipe and the upper air duct 41 to prevent air leakage. This embodiment does not make specific limitations on this.

[0092] In some embodiments, such as Figure 7 As shown, in the vertical direction, the first side air outlet 142 and the second side air outlet 143 are at the same height. If the first side air outlet 142 and the second side air outlet 143 are not at the same height, the resistance characteristics of the airflow from the upper air duct 41 to the first side air outlet 142 and the second side air outlet 143 will be different, resulting in uneven airflow from the first side air outlet 142 and the second side air outlet 143.

[0093] Therefore, in this embodiment, by setting the first side air outlet 142 and the second side air outlet 143 to the same height, the airflow resistance characteristics of the airflow from the upper air duct 41 to the first side air outlet 142 and the second side air outlet 143 are completely consistent, thereby ensuring that the air volume and air pressure of the air outlets on both sides are balanced. This allows cold air to cover the left and right spaces of the room synchronously and equally, and to sink evenly, eliminating the possible left and right temperature differences in the room and achieving temperature uniformity and comfort.

[0094] Furthermore, the first side air outlet 142 and the second side air outlet 143 are at the same height, which can adopt a standardized design of symmetry or mirror image, greatly simplifying the process of mold development, production assembly and quality inspection. This not only reduces production costs, but also ensures the stability and consistency of the performance of each product in mass production.

[0095] In some embodiments, such as Figure 7 As shown, the first side air outlet 142 and the second side air outlet 143 have the same area. The area of ​​the first side air outlet 142 and the second side air outlet 143 is closely related to the air volume and velocity they can blow out. By setting the first side air outlet 142 and the second side air outlet 143 to have the same area, and in conjunction with the same height, it is ensured that the airflow leaving the first side air outlet 142 and the second side air outlet 143 has consistent air volume, air pressure, and air velocity, thereby providing symmetrical air supply to the indoor space and improving the uniformity of the temperature field. Furthermore, based on the same air velocity, the airflow noise generated by the first side air outlet 142 and the second side air outlet 143 is uniform in sound pressure level and spectral characteristics, eliminating the auditory discomfort caused by noise asymmetry, making the operating sound effect more stable and uniform, and providing users with a more excellent overall quiet effect. In addition, the same air outlet kinetic energy ensures that the two airflows blown from the first side air outlet 142 and the second side air outlet 143 have the same projection distance, can reach the two side boundaries of the room at the same time, and sink down along the wall at the same time, thus creating a symmetrical indoor air circulation heat exchange system.

[0096] In some embodiments, the area of ​​the first side air outlet 142 and the second side air outlet 143 is 3500 mm². 2 ~4450mm 2The size of the first side air outlet 142 and the second side air outlet 143 will affect the air outlet resistance and air volume of the first side air outlet 142 and the second side air outlet 143.

[0097] If the area of ​​the first air outlet 142 and the second air outlet 143 is less than 3500 mm² 2 This means that the air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 is too small. At the rated airflow of the fan 3, this results in excessively high airflow velocity at the first side air outlet 142 and the second side air outlet 143. The high-speed airflow violently rubs against the edges of the first side air outlet 142 and the second side air outlet 143, generating aerodynamic noise and affecting the user experience. Furthermore, the small air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 increases the flow resistance as the air passes through them, leading to a decrease in the air volume delivered by the first side air outlet 142 and the second side air outlet 143, thus affecting the overall heat exchange efficiency of the wall-mounted air conditioner indoor unit 100.

[0098] If the area of ​​the first air outlet 142 and the second air outlet 143 is greater than 4450 mm² 2 This means that the air outlet areas of the first side air outlet 142 and the second side air outlet 143 are too large. This will result in insufficient airflow speed from the first side air outlet 142 and the second side air outlet 143, and the airflow cannot be effectively delivered to the far end of the room, weakening the effect of lateral air supply in promoting indoor air heat exchange and easily causing uneven temperature distribution. Furthermore, having excessively large first side air outlets 142 and the second side air outlet 143 on the first side panel 11 and the second side panel 12 will affect the structural strength of the first side panel 11 and the second side panel 12, and will also be aesthetically unappealing. It should be noted that since the first side air outlet 142 and the second side air outlet 143 need to have sufficient length, if the first side air outlet 142 and the second side air outlet 143 are too large, the width of the first side air outlet 142 and the second side air outlet 143 must be increased. While keeping the size of the casing 1 unchanged, this will result in a reduction in the width of the casing air inlet 13, leading to a smaller air intake space. Furthermore, the excessively large area of ​​the first side air outlet 142 and the second side air outlet 143 will cause the first side air outlet 142 and the second side air outlet 143 to be closer to the air outlet side of the fan 3 in the vertical direction, which will result in the airflow not being able to travel a sufficient distance in the upper air duct 41, and thus the airflow will not be easy to blow out from the first side air outlet 142 and the second side air outlet 143, thus failing to achieve air outlet on both sides.

[0099] Therefore, in this embodiment, the area of ​​the first side air outlet 142 and the second side air outlet 143 is set to 3500 mm². 2 ~4450mm 2This design minimizes airflow resistance from the first and second side air outlets 142 and 143, ensuring sufficient airflow and reducing their encroachment on other components, thus maintaining a harmonious and aesthetically pleasing appearance. Furthermore, it avoids the situation where excessively large areas of the first and second side air outlets 142 and 143 would result in them being too close to the air outlet side of the fan 3 in the vertical direction, preventing insufficient airflow within the upper duct 41 and hindering airflow from exiting the first and second side air outlets 142 and 143. This design ensures smooth airflow from both sides.

[0100] It should be noted that the area of ​​the first side air outlet 142 and the second side air outlet 143 can be 3500 mm². 2 3700mm 2 3900mm 2 4100mm 2 4300mm 2 Or 4450mm 2 This embodiment does not impose specific limitations on this.

[0101] For example, the area of ​​the first side air outlet 142 and the second side air outlet 143 is 4450 mm². 2 At this time, the air volume of the first side air outlet 142 and the second side air outlet 143 is larger, the resistance to the outflowing air is smaller, and the first side air outlet 142 and the second side air outlet 143 occupy less space for other components, thus achieving a balance in terms of air volume, airflow resistance and space occupation.

[0102] It should be noted that the shapes of the first side air outlet 142 and the second side air outlet 143 can be various shapes such as circular, elliptical, rounded rectangle, and rectangular, as long as the area of ​​the first side air outlet 142 and the second side air outlet 143 is 3500 mm². 2 ~4450mm 2 This embodiment does not impose any specific limitations on this.

[0103] In some embodiments, such as Figure 9 As shown, along the front-rear direction of the housing 1, the width M of the first side air outlet 142 and the second side air outlet 143 is 28mm to 42mm.

[0104] It should be noted that the front-to-back direction of housing 1 is... Figure 9 The direction from left to right or from right to left.

[0105] When the width M of the first side air outlet 142 and the second side air outlet 143 is less than 28mm, it means that the width M of the first side air outlet 142 and the second side air outlet 143 is too small, which will reduce the air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 along the front and rear direction of the casing 1, resulting in a reduction in air volume.

[0106] When the width M of the first side air outlet 142 and the second side air outlet 143 is greater than 42mm, it means that the width M of the first side air outlet 142 and the second side air outlet 143 is too large, which will cause the size of the casing 1 in the front and rear direction to increase, resulting in the thickness of the whole unit being too thick and excessively increasing the space occupied in the room.

[0107] Therefore, in this embodiment, by setting the width M of the first side air outlet 142 and the second side air outlet 143 to be 28mm to 42mm along the front-back direction of the casing 1, it ensures that the first side air outlet 142 and the second side air outlet 143 have sufficient air outlet area along the front-back direction of the casing 1, and ensures the air volume of the first side air outlet 142 and the second side air outlet 143, without excessively increasing the size of the casing 1 in the front-back direction, thus avoiding excessive increase in the space occupied by the wall-mounted air conditioner indoor unit 100.

[0108] It should be noted that the width M of the first side air outlet 142 and the second side air outlet 143 are equal along the front-rear direction of the housing 1, so as to ensure that the air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 is the same in the front-rear direction of the housing 1.

[0109] It should be noted that the width M of the first side air outlet 142 and the second side air outlet 143 can be 28mm, 30mm, 32mm, 35mm, 37mm, 40mm or 42mm, and this embodiment does not make a specific limitation on this.

[0110] For example, along the front-rear direction of the housing 1, the width M of the first side air outlet 142 and the second side air outlet 143 is 37mm. At this time, the first side air outlet 142 and the second side air outlet 143 have the optimal air outlet area along the front-rear direction of the housing 1, ensuring that the air volume of the first side air outlet 142 and the second side air outlet 143 is larger, and also ensuring that the size of the housing 1 in the front-rear direction is smaller.

[0111] In some embodiments, such as Figure 9 As shown, in the vertical direction, the length L of the first side air outlet 142 and the second side air outlet 143 is 125mm to 155mm.

[0112] When the length L of the first side air outlet 142 and the second side air outlet 143 is less than 125mm, it means that the vertical dimensions of the first side air outlet 142 and the second side air outlet 143 are too small, which will reduce the air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 in the vertical direction, increase the air outlet resistance of the first side air outlet 142 and the second side air outlet 143, and thus reduce the air volume of the first side air outlet 142 and the second side air outlet 143.

[0113] When the length L of the first side air outlet 142 and the second side air outlet 143 is greater than 155mm, it means that the vertical dimensions of the first side air outlet 142 and the second side air outlet 143 are too large, which will increase the vertical dimensions of the casing 1 and thus increase the space occupied by the wall-mounted air conditioner indoor unit 100.

[0114] Therefore, in this embodiment, by setting the length L of the first side air outlet 142 and the second side air outlet 143 to 125mm to 155mm, the air outlet area of ​​the first side air outlet 142 and the second side air outlet 143 in the vertical direction is guaranteed without increasing the vertical dimension of the casing 1, and the air volume of the first side air outlet 142 and the second side air outlet 143 is guaranteed.

[0115] It should be noted that, in the vertical direction, the length L of the first side air outlet 142 and the second side air outlet 143 can be 125mm, 130mm, 135mm, 140mm, 143mm, 150mm or 155mm, and this embodiment does not make a specific limitation on this.

[0116] For example, in the vertical direction, the length L of the first side air outlet 142 and the second side air outlet 143 is 143mm. At this time, the first side air outlet 142 and the second side air outlet 143 have the optimal air outlet area in the vertical direction, which ensures that the air volume of the first side air outlet 142 and the second side air outlet 143 is larger, and also ensures that the size of the casing 1 in the vertical direction is smaller.

[0117] In some embodiments, such as Figure 9 As shown, the air duct component 4 also includes a volute 44, which is located on the rear side of the fan 3 and is arranged around a portion of the fan 3.

[0118] The air duct component 4 also includes a volute tongue 45, which is located on the front side of the fan 3 and is positioned opposite to the volute housing 44.

[0119] It should be noted that, in the vertical direction, the space formed by the volute tongue 45 and the volute casing 44 near the upper air duct 41 and the lower air duct 42 is the air outlet side of the fan 3, and the space formed by the volute tongue 45 and the volute casing 44 near the air inlet 13 of the casing is the air inlet side of the fan 3.

[0120] In the vertical direction, the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 is 60mm to 75mm.

[0121] When the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 is less than 60mm, it means that the distance the air conditioning air travels along the upper air duct 41 after being blown out from the air outlet side of the fan 3 is too short. This will cause the air conditioning air to face the outlet resistance of the first side air outlet 142 and the second side air outlet 143 after being blown out from the air outlet side of the fan 3. As a result, the air conditioning air blows forward after being blown out from the first side air outlet 142 and the second side air outlet 143, without being guided to the space on both sides.

[0122] When the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 is greater than 75mm, it means that the air conditioning air blown out from the air outlet side of the fan 3 travels too far along the upper air duct 41. The air conditioning air travels too far along the upper air duct 41, which will cause more flow loss of the air conditioning air, and thus reduce the air volume of the first side air outlet 142 and the second side air outlet 143.

[0123] In this embodiment, by setting the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 to be 60mm to 75mm, the air conditioning air is ensured to have sufficient flow distance in the upper air duct 41. This avoids the air conditioning air from directly facing the outlet resistance of the first side air outlet 142 and the second side air outlet 143 from the air outlet side of the fan 3. This ensures that the air conditioning air can be blown to both sides after being blown out from the first side air outlet 142 and the second side air outlet 143, and also ensures the air volume of the first side air outlet 142 and the second side air outlet 143.

[0124] It should be noted that, in the vertical direction, the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 can be 60mm, 65mm, 68mm, 70mm or 75mm, and this embodiment does not make a specific limitation on this.

[0125] For example, in the vertical direction, the distance H from the lower end of the first side air outlet 142 to the lower end of the volute tongue 45 is 68mm. At this time, the flow loss of the air conditioning air in the upper air duct 41 is minimized, which makes the air volume blown out by the first side air outlet 142 and the second side air outlet 143 larger, and the air conditioning air can be effectively blown from the first side air outlet 142 and the second side air outlet 143 to the space on both sides.

[0126] In some embodiments, see Figures 9 to 12 The air duct 4 also forms a main air duct 46. The air inlet end 461 of the main air duct 46 is connected to the air outlet side of the fan 3, and the air outlet end 462 of the main air duct 46 is connected to the upper air duct 41 and the lower air duct 42 respectively.

[0127] The housing 1 also includes an air guide 5, which is rotatably mounted within the main air duct 46 and can switch between an open position, a first position, a second position, and a diversion position. Figure 9 As shown, when the air guide 5 is in the open position, both the upper air duct 41 and the lower air duct 42 are connected to the air outlet 462 of the main air duct 46. Figure 11 As shown, when the air guide 5 is in the first position, the air guide 5 can close the lower air duct 42, so that the upper air duct 41 is connected to the air outlet 462 of the main air duct 46. Figure 10 As shown, when the air guide 5 is in the second position, the air guide 5 can close the upper air duct 41, so that the lower air duct 42 is connected to the air outlet 462 of the main air duct 46. Figure 12 As shown, when the air guide 5 is in the diversion position, the air guide 5 is configured to divert the airflow sent out by the main air duct 46 so that the diverted airflow enters the upper air duct 41 and the lower air duct 42 respectively.

[0128] The air guide 5, which rotates within the main air duct 46, enables the wall-mounted air conditioner indoor unit 100 to operate in four modes. When the air guide 5 is in the open position, both the upper air duct 41 and the lower air duct 42 are connected to the air outlet 462 of the main air duct 46. At this time, the wall-mounted air conditioner indoor unit 100 operates in the up-and-down air outlet mode, and the air conditioning air can be blown into the room from the upper air outlet 144, the lower air outlet 141, the first side air outlet 142, and the second side air outlet 143. When the air guide 5 is in the first position, the wall-mounted air conditioner indoor unit 100 operates in the up-and-down air outlet mode, and the air guide 5 directs the air from the lower air duct... When 42 is closed, the air conditioning air is blown into the room from the upper air outlet 144, the first side air outlet 142, and the second side air outlet 143. When the air guide 5 is in the second position, the wall-mounted air conditioner indoor unit 100 operates in the downward air outlet mode, and the air guide 5 closes the upper air duct 41, allowing the air conditioning air to be blown into the room from the lower air outlet 141. When the air guide 5 is in the diversion position, the wall-mounted air conditioner indoor unit 100 operates in the on-demand distribution mode. At this time, the air conditioning air in the main air duct 46 can be distributed to the upper air duct 41 and the lower air duct 42 in a certain proportion through the air guide 5 to meet the user's needs. In this way, the rotation of the air guide 5 realizes the switching of multiple air supply modes to meet the needs of diverse scenarios.

[0129] It should be noted that the air guide 5 can be an air guide plate, a louvered air guide blade, or other structures that can achieve the function of the air guide 5. This embodiment does not make specific limitations on this.

[0130] For example, the air guide 5 is an air guide plate, which has an airfoil or plate-like structure. One side of the air guide plate is rotatably connected to the duct wall of the main air duct 46 via a rotating shaft. This rotating shaft can be driven by a motor (e.g., a stepper motor) to achieve precise control of the rotation angle of the air guide plate. When the air guide plate is in the open position, its plate surface is approximately parallel to the airflow direction, and it does not obstruct the inlets of the upper and lower air ducts, allowing the airflow to enter both ducts simultaneously without obstruction. When the air guide plate rotates to the first position, its plate rotates and completely covers the inlet of the lower air duct, acting like a built-in valve, thereby sealing and closing the lower air duct and forcing all airflow into the upper air duct. When the air guide plate rotates to the second position, its plate rotates in the opposite direction and completely covers the inlet of the upper air duct, thereby sealing and closing the upper air duct and forcing all airflow into the lower air duct. When the air guide plate is in the diversion position, its plate rotates to a specific angle between the open position and the first (or second) position. At this point, the plate acts as a flow divider, splitting the airflow from the main duct into two parts. One part of the airflow is guided by the guide plate into the upper duct, while the other part enters the lower duct from below the guide plate. By controlling the angle of the guide plate, the airflow ratio between the upper and lower ducts can be adjusted. The guide plate has a simple and reliable structure and is inexpensive.

[0131] Of course, the air guide 5 can also consist of a group (at least two) of small guide vanes that can be controlled independently or in conjunction. These vanes are arranged side by side at the outlet of the main air duct 46, forming a louvered air guide vane structure. All vanes are open, corresponding to the open position. All vanes deflect downwards synchronously, blocking the lower air duct inlet, corresponding to the first position. All vanes deflect upwards synchronously, blocking the upper air duct inlet, corresponding to the second position. By controlling the deflection angle of different vanes, the ratio of the opening area to the upper and lower air ducts can be adjusted, thereby achieving air diversion at the diversion position. The multi-blade design allows for more flexible control of airflow distribution, enabling more complex air delivery modes. Furthermore, it can disperse and distribute the airflow more evenly to the target air duct, avoiding the problem of uneven airflow on both sides that may be caused by a single air guide vane.

[0132] In some embodiments, combined with Figure 1 and Figure 13 The housing 1 is also provided with a first air guide plate 6, which is rotatably set at the upper air outlet 144 to open or close the upper air outlet 144.

[0133] The housing 1 is also provided with a second air guide plate 7, which is rotatably set at the lower air outlet 141 to open or close the lower air outlet 141.

[0134] When the first air guide plate 6 closes the upper air outlet 144 and the second air guide plate 7 closes the lower air outlet 141, the wall-mounted air conditioner indoor unit 100 operates in side air outlet mode. At this time, both the upper air outlet 144 and the lower air outlet 141 are closed, and only the first side air outlet 142 and the second side air outlet 143 are open. After the air conditioner air is blown out from the air outlet side of the fan 3, the flow resistance is the greatest because the upper air outlet 144 and the lower air outlet 141 are closed, while the flow resistance is small because the first side air outlet 142 and the second side air outlet 143 are open. Under the action of pressure, all the air conditioner air will be blown out from the first side air outlet 142 and the second side air outlet 143. In this way, by simply closing the upper air outlet 144 and the lower air outlet 141 with the first air guide plate 6 and the second air guide plate 7, the air conditioning air is blown out from the first side air outlet 142 and the second side air outlet 143 under pressure. There is no need to set up a separate drive mechanism to drive the air conditioning air out from the first side air outlet 142 and the second side air outlet 143, thus saving manufacturing costs.

[0135] In some embodiments, the first side air outlet 142 and the second side air outlet 143 may be provided with air outlet grilles (not shown in the figure). The air outlet grilles can disperse the air from the first side air outlet 142 and the second side air outlet 143 to achieve a soft wind effect. In addition, the air outlet grilles can prevent dust and other impurities from the outside from entering the interior of the wall-mounted air conditioner indoor unit 100 from the first side air outlet 142 and the second side air outlet 143.

[0136] In some embodiments, the first side air outlet 142 and the second side air outlet 143 may also be provided with a third air guide plate and a fourth air guide plate. The third air guide plate is rotatably disposed at the first side air outlet 142, and the fourth air guide plate is rotatably disposed at the second side air outlet 143. The opening and closing of the first side air outlet 142 and the second side air outlet 143 are achieved by rotating the third air guide plate and the fourth air guide plate. When the wall-mounted air conditioner indoor unit 100 is not in use, the first side air outlet 142 and the second side air outlet 143 can be closed by using the third air guide plate and the fourth air guide plate to ensure the consistency of the appearance of the wall-mounted air conditioner indoor unit 100.

[0137] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
